Step 6
What to Do Next
Configure BFD bring up timeout interval.
Once LSP is signaled and BFD session is created, TE allows given time for the BFD session to come up. If
BFD session fails to come up within timeout, the LSP is torn down. Hence it is required to configure BFD
bring up timeout
Configuring BFD Bring up Timeout
Perform these steps to configure BFD bring up timeout interval. The default bring up timeout interval is 60
seconds.

RP/0/RSP0/CPU0:router(config)#interface
tunnel-te 65535
Step 2
Enables the time interval (in seconds) to wait for the BFD
session to come up.
bfd bringup-timeout seconds
Example:
